Aftermarket Radiator overflow?

I bought a used prius, I fell into a scam knowing nothing about the car and found out the car had $2700 worth of damages. Shame on me. Now i'm stuck with a car that needs to be worked on and I need some help. There was a crack in the radiator that I think I just fixed (temporarily) while I am searching the market for another radiator and assembly and raising money to pay for it. One of the challenges is that the Radiator Overflow reservoir is totally smashed and the tube that goes to it from the radiator just pours out onto the ground. I was wondering if anyone has used an aftermarket part to solve this issue? I was thinking of trying to use a universal overflow/return but I wanted to see if anyone has found a way around having to buy a whole new fan assembly to replace the overflow.
